2012 Audi TDI with Alarm Horn issue

Hi all,

I few days ago I realized that my car's key fob is starting to get finicky. I would need to stand close to the car before it would respond and then it stopped making the beep/horn sound when I lock it. The doors would still lock and unlock fine.

Just really bothered that it is not working like before.

The only thing I can't think of is the:

01134 - Alarm Horn (H12)
004 - No Signal/Communication

I checked all the fuse, no issues there. So maybe the horn just went dead? If that is the case, is it easy to replace? Where is it located?

The part number looks like it has superseded to a [1K0-951-605-F]. You can use an internet search of that part number to see what the H12 looks like.

They are easy to replace and do not require any special procedures with VCDS other than clearing the codes. That is if the H12 has failed, also check the wiring/connections for damage, rodent bites, etc.
